Maternal Obesity Speeds Up Offspring Aging, Increasing Diabetes & Heart Disease Likelihood

Kids of obese mothers are more likely to age faster and develop diabetes and heart disease, reveals a new study. The findings of the study are published in The Journal of Physiology.

It has long been known that obesity impairs our metabolism and predisposes to diabetes and heart disease.

Mantra to Prevent Childhood Obesity � Vigorous Physical Activity
Being physically very active is the mantra to prevent pediatric obesity rather than concentrating efforts at restricting energy consumption.

Researchers at the Salvador Zubiran National Institute of Medical Sciences and Nutrition in Mexico City and the University of Wyoming at Laramie studied offspring of obese rat mothers. They observed the offspring throughout their lives (puberty, early adult life, late adult life, and early aging) to determine the rate at which they aged. Offspring of obese mothers had more body fat and showed early pre-diabetic signs such as an early rise in insulin resistance, increasing susceptibility to diabetes.

Offspring of the obese mothers also showed the impaired function of their mitochondria, the power stations of cells that generate the energy cells need to function properly. These changes make it more likely that organisms will develop heart disease. Interestingly, some of the unwanted outcomes resulting from maternal obesity were different in males and female offspring. The reason for this is not clear, but it is thought to be hormonal in nature.

Encouragingly, the exercise by the offspring improves many of the poor offspring outcomes that result from maternal obesity. These new findings add to the accumulating evidence for the influence of conditions in the womb and early life, on the physiology of the offspring, which thus impacts their susceptibility for diseases and the rate at which they age.

Obesity - Causes, Symptoms, Diagnosis, Complications, Treatment
Obesity is a condition where there is excess accumulation of body fat which poses a risk to the health of the individual. It can affect children and adults.

Elena Zambrano, the senior author on the study, commented on the research saying:

"This reinforces the link between maternal obesity and the aging of offspring, specifically around the increased likelihood of developing diabetes and heart disease. Encouragingly, in previous studies, we have shown that exercise by the offspring can off help offset the risks brought about by maternal obesity."

Carbohydrates and Its Role in Obesity
Over 1 billion people world-wide are obese thus affecting their health due to their nutrition and lifestyle. 3.9% of India’s population is obese! Know more about obesity and its prevention.

Malnutrition to Obesity - The Big Leap
Obesity is the root cause of problems like diabetes, heart disease, stroke, arthritis and gall bladder disease. A serious look at our strategies is needed to tackle this fast growing epidemic.
